Bluez Dubbing
What it is
Bluez Dubbing is an open-source pipeline for automatic video dubbing and subtitle generation, offered through a web interface, API, or self-hosted setup. It can create dubbed video with subtitles burned in, translate audio without subtitles, or produce subtitles alone. The maker says it supports more than 50 languages with automatic language detection. WhisperX provides speech recognition, word-level timestamps, and speaker diarization, while speaker matching is supported. Translation options include M2M-100 and deep-translator; speech can use Chatterbox voice cloning or Edge TTS. Voice activity detection and time stretching align replacement speech with the video. Subtitle styles include Netflix, bold desktop, and mobile optimized. The web UI accepts file uploads and links from YouTube, Instagram, and TikTok, with progress tracking, previews, and downloads. REST endpoints and command-line tools support automation. Recognition, translation, and speech models can be swapped independently or replaced with user models. It is free under the Apache 2.0 license.
